HEllo Christopher,
Yes, it looks true.
In the older version (pre-release of mod6 and older) chainbreaks are OK
in the alignment, in the current version (mod6v0) they cause problems.
Only those chainbreak characters, that are within a sequence, not the
ones, that separate heteroatoms.
On the other hand, you do not need to include them in the sequence,
Modeller will automatically assume a chain break, if there is a longer
than usual bond distance.
I hope, removing chain breaks from your seq will make your top file
work, if not, let us know.
best wishes,
Andras
